Whole effluent samples were collected for use in a chronic Ceriodaphnia dubia pass/fail toxicity test. The test passed utilizing these samples. The report should be self-explanatory; however, should you have any questions concerning this report,please do not hesitate to contact Ms. Carol Hollenkamp at(919) 743-8450 and/or Mr. Wes Bell at(704)235-2192, or at carol.hollenkampca)ncdenr.gov and wes.bell(ncdenr.gov.

The City of Lowell WWTP has an effluent discharge permitted at 0.6 MGD entering the South Fork Catawba River(7Q10 of 124 CFS). The test using these samples resulted in a Pass. Toxicity test information follows: Test Type 3-Brood Ceriodaphnia dubia chronic pass/fail Test Concentration 0.74% sample Test Result PASS Control Survival 100% Control Mean Reproduction 25.3 neonates Test Treatment Survival 100% Treatment Mean Reproduction 25.8 neonates First Sample pH 7.12 SU First Sample Conductivity 531 micromhos/cm First Sample Total Residual Chlorine <0.10 mg/I Second Sample pH 6.96 SU Second Sample Conductivity 474 micromhos/cm Second Sample Total Residual Chlorine <0.10 mg/1 Test run by Aquatic Toxicity Unit(ATU)had a control organism reproduction of 72%,which does not meet the 80%3rd brood control reproduction as required by NC protocol for compliance testing. Because the test organism reproduction was greater than the control reproduction,all other test criteria were met, and the EPA requirement of 60% 3rd brood reproduction was met,the test is considered valid for the toxicity sampling event.

Lowell WWTP has an effluent discharge permitted that is 0.6 million gallons per day(MGD)entering the south fork of the Catawba River(7Q10 of 124.0 CFS). Whole effluent samples were collected on July 23 and July 25 by Donna Hood and facility representative Timothy Barnes for use in a chronic Ceriodaphnia dubia pass-fail toxicity test. The test passed for the purposes of the toxicity inspection. Toxicity test information follows. Test Type 3-Brood Ceriodaphnia dubia chronic pass fail Test Concentrations 0.74% Test Result Pass(For Toxicity Inspection) Control Survival 100% Control Mean Reproduction 25.3 neonates Test Treatment Survival 100% Treatment Mean Reproduction 25.8 neonates First Sample pH 7.12 SU First Sample Conductivity 531 micromhos/cm First Sample Total Residual Chlorine <0.10 mg/L Second Sample pH 6.96 SU Second Sample Conductivity 474 micromhos/cm Second Sample Total Residual Chlorine <0.10 mg/L The test run by ATU had a control organism reproduction of 72%,which does not meet the 80%ri brood control reproduction as required by NC protocol for compliance testing. However,this test is not used for reporting compliance,but rather to complete the requirements of a toxicity inspection. Because the test organism reproduction was greater than the control reproduction,all other test criteria were met,and the EPA requirement of 60%3`d brood reproduction was met,the test is considered valid for the toxicity inspection.

You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity violation(s). Your efforts may include conducting a Toxicity Reduction Evaluation (TRE), a site-specific study designed to identify the causative agents of effluent toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity control options, and confirm reductions in effluent toxicity. Please be aware that North Carolina General Statutes provide for assessment of civil penalties for violations of NPDES permit limitations and requirements. The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring and Reporting Requirements. Please note appropriate mailing addresses for submitting your Discharge Monitoring Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. We encourage you to review this information; if it would be helpful to discuss this situation or possible solutions to resolve effluent toxicity noncompliance, please contact Mr. John Giorgino with this office at(919) 733-2136.
